Years ago I purchased my first scope from a big box store like many others and after some time was discouraged by the lack of quality. I was busy, so lost interest in pursuing it further. It was this 4.5 inch Meade reflector on an Alt/Az Go To mount.
My desire now is to be able to photograph the objects I like to view, so I upgraded again to this Explore Scientific Maksutov-Newtonian. It has a meniscus correct lens at the front, a spherical primary mirror and elliptical flat secondary. This gives a flat field, coma free, color aberration free, and no star spikes from secondary mirror support veins.
152 mm mirror
731mm focal length
f/4.8 focal ratio
I use a Canon T3i for the imaging camera, a ZWO 120MC for guide camera which doubles as a planetary camera on the Dobsonian. The scope is mounted on a Celestron AVX equatorial mount.
